Today we delve into the algebra of matrices. Everything you learned to do with numbers in arithmetic such as multiplying or reciprocating you get to learn to do with matrices. Practice working the problems algebraically and electronically. See the class calendar for links to my Calculator Guide to Matrix Algebra and Calculator Guide to Determinants.
